Flexible Display Support Plate with Segmented Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flexible display devices face challenges in providing a robust and stable support system that ensures the display module remains securely attached and evenly supported, especially when the device is folded or extended.
Innovation Solution
The implementation of a support system comprising a support plate with a flat and flexible part, and support bars that are more firmly coupled through upper and lower connecting parts, along with an adhesive layer in specific configurations, to enhance the structural integrity and flexibility of the display device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a flexible part is added to the support plate to enable folding, then the device becomes more adaptable and portable, but the structural stability and support firmness deteriorate
Solution Approach 1:
The support plate is segmented into a flat part and a flexible part, allowing the device to be divided into stable and adaptable sections. The flat part maintains structural stability while the flexible part enables folding, resolving the contradiction between stability and adaptability.
Solution Approach 2:
Different parts of the support plate have different properties: the flat part provides rigidity and stability, while the flexible part provides adaptability and foldability. This local differentiation allows the overall structure to achieve both stability and folding capability simultaneously.
2Ease of operation
If the support plate is made more flexible to improve portability, then the device becomes easier to carry, but the support firmness and image quality deteriorate
Solution Approach 1:
The support plate is divided into a flat part for stability and a flexible part for portability. This segmentation allows the device to be portable when folded while maintaining support firmness when the flat part is engaged during display operation.
Solution Approach 2:
The flexible part provides portability through foldability, while the flat part provides support firmness through rigidity. Each part performs its specialized function locally, ensuring both portability and reliable support during operation.
3Strength
If connecting parts are added to firmly couple the support plate and support bar, then the structural integrity improves, but the device complexity increases
Solution Approach 1:
The connecting parts integrate the flat part and flexible part into a unified support structure. By merging these components through standardized connections, the structure achieves high integrity without requiring complex assembly mechanisms, thus improving strength while controlling complexity.

AI summary
A display device includes a display module, a support plate that is disposed on a lower surface of the display module and that includes a flat part and a flexible part that extends from the flat part in a first direction and that is folded about a bending axis that extends in a second direction crossing the first direction, a support bar that is disposed on a lower surface of the flexible part and that extends in the second direction, an upper connecting part that extends from an upper surface of the flexible part into the support bar through the flexible part, and a lower connecting part that extends from a lower surface of the support bar into the flexible part through the support bar.
